This paper presents the Simplified Method for Clusters Identification (the MIDAS method) used for grouping parts and machines in cellular manufacturing. The proposed method identifies and eliminates the exceptional elements of the incidence matrix as a way to obtain a perfect diagonal structure. The aplication of MIDAS method demonstrates that the method is useful and more simplified than the traditional grouping algorithms. The results permit the analyst deals with several solution alternatives and chooses the most effective one.

Material handling system design plays an important rule in many manufacturing systems. Many times this design is a complex task, as it’s integrated to the whole system. The design engineer should feel the impact on facilities layout, logistics policy and production policy. In this paper we discuss the influence of the manufacturing system model in Automated Guided Vehicles simulations. We present an Arena implemented example of a flow path layout, where models of different escopes and levels were used in order to feel the influence of the manufacturing system in the material handling system model performance. We compare a complex just-in-time model, where most of the production features were modeled, with a simple model, where the production system is modeled just as vehicles jobs.

In industrial manufacturing, product inspection is an important step in the production process. Automated visual inspection has been an active field of research during the last few years. However, very litlle has been increased in the production lines of textile. This paper investigates the use of segmentation techniques to automatically detect defects on textile industry and presents some examples of the defects which can be usually found. It also compares the efficiency, in quality control, of methods such as thresholding and edge detection.

This article presents initially the evolutive and cumulative process of the market trends along time. These market tendences are the reasonable price, quality and variety of products, as well as customized product. Then it is analised the influence of these requeriments on the enterprise as a whole, and especifically on the marketing and manufacturing functions. Thus, the need for development the flexibility of the marketing function risen due these market trend. In the last part it is developed the concept of flexibility of the marketing-mix, with the aim of linking the requeriments of the customer by a more variety and customized product with the approachs of the manufacturing functions for answer the market challenges.

The industrial competitiveness increase has the obliged the companies to review their manufacturing procedures in a way of making possible the costs reduction, productivity and quality enhance. It is verified that the organization and cut tools adequated controls allow many production inconveniencies reduction in the metal mechanic sector companies that employ machined manufacturing process. The tools management techniques can be this way used as an important information administration and the manufacturing process maximization manner. The association of the tool management phylosophy with the ISO 9000 Norms requirements has allowed that more efficient and trustable controls could be specially adapted to the process control items links.

Manufacturing companies face nowadays the problem of exponential growth of complexity in their market relations associated with the costumer changing expectations. Nevertheless, if this situation imposes new threats, it also brings new opportunities, by the introduction of new manufacturing organization models. However, the risks involved in introducing these models are very high, due to the radical changes involved. New simulation tools open the opportunity to test new solutions with low risk and low investment. This paper describes the SOMA, an organic and autonomous manufacturing system with some innovating characteristics, based on distributed and autonomy concepts. Following, it is discussed the modeling approach, supported by dynamic simulation tools. The results allow to foresee and evaluate the system potential for small batch production, with good flexibility and reliability.

This work describes a methodology based on a data acquisition system used as a tool for the performance analysis of welders based on the evaluation of the voltage and current behaviour acquired during experimental welding. The signals filtered by the use of Fast Fourier Transform and standard deviations analysis of the signal processed grant a quick evaluation about the skill of welders. To evaluate the methodology a series of tests performed by an authomatic machine and a welder was compared. The results shows the superiority of the authomatic welding, as expected. As a consequence of this study, the methodology described can be an effective method for the approval of welders in a procedure qualification requirement or as an alternative procedure for welders training system to be used in shop floors.

As an activity, design is closely related to field market, everyday becoming more competitive and global worldwide. This statement is a reality overflowing enterprises and has meant that design is becoming a strategical element for its unfolding, in such a way that design today acquires a gravitating role in the survival and competitive support of these enterprises. In the framework of a free market economy developed in Chile, the national metalmechanic sector does not escape from these premises and it requires support so to correctly back up en increasing effort to power design in order to add value to its products, improving itsm presence in the present markets as well as in the potential markets, such as Nafta and Mercosul. In that perspective, the project takes forward to promote development strategies of new products from a reality diagnose of design in this enterprise and from the analysis compared to the theories and methodologies of usual designs or developing designs in the industrialized countries. Knowledge of these theories (systematic, integrating, axiomatic) and the methodologies springing from them, will enable the elaboration of a solution fan of interest which will promote the model generation, appropriated to product development experimental type, adequated to the reality of the enterprise in question and strategically in terms of their markets. The limits of these models and asking proposals will be determined by series of factors alienated to design among which are presumably found : human factor, organization maturity, available manufacture means, and input reliability.
